7 Detailed Description
TLC2274-HT
SGLS416 – JANUARY 2015
7.1 Overview
The TLC2274 device exhibits rail-to-rail output performance for increased dynamic range in single- or split -
supply applications. These device offers comparable ac performance while having better noise, input offset
voltage and power dissipation than existing CMOS operational amplifiers. The TLC2274 device, exhibiting high
input impedance and low noise, is excellent for small signal conditioning for high-impedance sources, such as
piezoelectric transducers. It offers increased output dynamic range, lower noise voltage, and lower input offset
voltage. This enhanced feature set allows the device to be used in a wider range of applications.

7.3 Feature Description
These devices use the Texas Instruments silicon gate LinCMOS™ process, giving them stable input offset
voltages, very high input impedances, and extremely low input offset and bias currents. In addition, the rail-to-rail
output feature with single- or split-supplies, makes this device a great choice when interfacing with analog-to-
digital converters (ADCs).
